which statement is true about theese triangles is true?

A)There are exactly three acute triangles

B)There are exactly three isosceles triangles

C)There are exactly three right triangles

D)There are exactly three scalene triangles ​

Answer:

Step-by-step explanation:

Begin by dividing both sides by -4 to get:

[tex]\frac{\sqrt{2} }{2}=sin2\theta[/tex] and then take the inverse sin of both sides to get

[tex]sin^{-1}(\frac{\sqrt{2} }{2})=2\theta[/tex] (the inverse sin undoes the sin on the right). Now we need to look on our unit circle to find the angles where [tex]sin(\frac{\sqrt{2} }{2})[/tex] is positive. There are 2 places. Sin is positive in both QI and QII. The angles are

[tex]\frac{\pi}{4},\frac{3\pi}{4}[/tex]. Therefore, our 2 equations are

[tex]\frac{\pi}{4}=2\theta[/tex]  and  [tex]\frac{3\pi}{4}=2\theta[/tex].  Solving the first equation:

[tex]\theta=\frac{\pi}{8}[/tex]

and the second equation:

[tex]\theta=\frac{3\pi}{8}[/tex]

Answer:

9x² + 6xy + y²

Step-by-step explanation:

(a + b)² =  a² + 2ab + b²

a  = 3x

b = y

(3x +y)² = (3x)² + 2*3x*y + y²

            = 9x² + 6xy + y²

(3x)² = 3²*x² = 3*3*x² = 9x²

Answer:

I don't know

Step-by-step explanation:

the answer is 0.2

The average of x and y is 03

The average of the three numbers is given as:

Average = 10

This means that:

(x + y + 24)/3 = 10

Multiply both sides by 3

x + y + 24 = 30

Subtract 24 from both sides

x + y = 6

Divide by 2

(x + y) = 3

Hence, the average of x and y is 03

Answer:

21

Step-by-step explanation:

The smallest number that can go into both 3 and 7 as our denominators is 21. This can be worked about by multiplying them together.

(FYI: In some cases, if the product is even, it may not always work to multiply them together)

Answer:

21

hope this helps

have a good day :)

Step-by-step explanation:

3 multiples are 3, 6, 9, 12, 15, 18, 21, 24

7 multiples are 7, 14, 21, 28

so would need to change both denominators to 21 and multiple 7 and to 1/3 to get 7/21 and 3 to 4/7 to get 12/21

Answer:

65 degrees

Step-by-step explanation:

Since it is given that AB=DC

then we know that AO=DO and BO=CO because it is the radius of a same circle.

Hence the shapes are equal and thus DOC=65 degree as it serves as a corresponding angle to AOB

Answer:

2.83 meters

Step-by-step explanation:

Change 217 cm to meter

217 * 1 m/ 100 cm = 2.17 m

5 meter - 2.17 m = 2.83 meters

Answer:

283 cm Or 2.83 m of cloths remaining after cutting.

Step-by-step explanation:

As we know that

1 m = 100 cm

so, 5 m = 5 × 100 = 500 cm

Subtract 217 cm from 500 cm

➛ 500 - 217

➛ 283 cm Or 2.83 m

Answer:

The correct option is (b).

Step-by-step explanation:

We need to find the equivalent to -2(4-3x)+(5x-2)

Using the associative property,

-2(4-3x) = -2(4)+2(3x)

= -8+6x

So,

-2(4-3x)+(5x-2) = -8+6x +5x-2

taking like terms together,

-2(4-3x)+(5x-2) = 6x+5x-8-2

= 11x-10

The equivalent expression is equal to (11x-10).

Answer:

C.-2.33

Step-by-step explanation:

We are given that

Significance level, [tex]\alpha =1[/tex]%=0.01

We have to find  the critical value of z  for a left-tailed test.

To find the critical value , we will use the z-table at significance level 0.01 for left-tailed test.

By using the z-table at significance level 0.01 for left-tailed test

The critical value of z at  1% significance level for left-tailed test

=-2.33

We get p-value by using z-critical value

P-value=0.0099<0.01

So, hypothesis  test would be reject the null hypothesis at  at 1% significance level.

Hence, the critical value of z=-2.33

Option C is true.

Answer:

5x = 11.

Step-by-step explanation:

-4x - 2y = -2

x    - 2y =  9  

Subtracting:

-4x - x - 2y - (-2y) = -2 - 9

-5x - 2y + 2y = -11

-5x = -11

5x = 11.

Answer:

x=100

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles

x+31 = 131

Subtract 31 from each side

x +31-31 = 131-31

x = 100
